The Schedule referred to in these Lettera Pat-en t and making part ofthe lame.

4T1: all 'whom it may concern:

Be it known that I, R. B. PRINDLE, of Norwich, in the county ofChenango, and in the State of New York, have invented certain new anduseful Improvements in Curtain-Fixtures; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, making apart of thisspecification, iu which- Figure 1 is a front elevation, showing myimproved xture as applied to a roller;

Figure 2 is a vertical cross-section of the same on the line x :c offig. 1; and

Figures 3 and 4 are side elevations of the bracket and leverrespectively.

Letters of like name and kindrefer to like parts in eachl of thefigures.

The nature of my invention consists in pivoting one end ofthe-curtaiu-roll within a slot having au upward and a forward curve, sothat when said roll is moved outward, it shall be raised, and release aratchet-wheel, secured to said roller, from engagement with a pin orother detent secured to the bracket, and, when liberated, saidrollersliall drop backward' and downward, -santo:uatically, so as to bringsaid ratchet-wheel'iuto engagement again with said pin or detent.

t also consists in the employment of a lever pivoted to the bracketabove and in rear of the roller, and provided with a vertical slot,through which `the pivot of said roller passes, substantially as and forthe purpose hereinafter shown.`

A represents the roller, havingsecured thereto a'curtain, B.

One end of said vroller is pivoted within a bracket,

. in the usual manner, while the opposite end is provided withl ametallic spool, C, the ilanges of which are formed byv a cap, c,covering the end of the roller, and

by aratchet-wheel, D.

A pivot, E, projects outward from the centre of the ratchet-wheel, andfurnishes an axial bearing for the roller.'

F represents a bracket, having a slot, f, corresponding in widthto thediameter of the pivot E, which curves upward land forward, as seen iniig. 3. When the roller is in place, with the pivot resting in thebottom of the slot, the teeth of the ratchet-wheel engage with a piu ordetent, x', secured to and projecting at a right angle therewith fromthe inner face of said bracket, so as to prevent the roller fromturning; but

if the roller be moved outward,'the pivot will slide upward in the slot,and release said ratchet-wheel Vfrom engagement with the detent, andpermit theroller to revolve freely.

To accomplish the latter result, a lever, G, of the shape shown in fig.4, is pivoted at its upper corner to the bracket, above and in rear ofthe pivot E, which pivot passes through a vertical slot, g, Within saidlever.

The lower end of the lever is bent inward at a right angle to its face,and is provided with -an opening for the passage of the cord H from thespool.

It' now the cord be brought forward, by the haud,it

will produce a like movement of the lever audroller, and release theratchet-wheel from engagement with the detent, so as to permitsaidroller to be revolved by saidcorfhand thecnrtilin raised or lowered,as may` be desired.

. Upon releasing the cord, the lever and roller drop downward andbackward, so as to bring the ratchetwheel into engagement with thedetent again, and at once arrest the motion of the roller.

Itis believed that this device is the most simple, durable, andconvenient of any that has ever been used for'a like purpose, and that,as `it can be furnished at a small cost, when once known, its generaladoption will be certain.

Having thus fully sct forth the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is

The within-described curtain-fixture, consisting of the spool C,ratchet-wheel D, or its equivalent, pivot E, bracket F, provided withthe curved slot f, and deteut x', and the lever G, provided with theslot g, all constructed and arranged substantially as and for thepurpose herein 'shown and described.

Also, the bracket F, provided with the curved slot f, in combinationwit-h the lever G, containing the vertical;- slot g, and pivoted abovesaid slot, substantially as herein shown and specified.

In! testimony that I claim the foregoing, I have hereunto set my hand,this 4th dayof May, 1869.

R. B. PRINDLE.
